New pumped storage hydro power plant comes online in China
15/2/2023
News
A new 1.2 GW pumped storage power plant has been successfully connected to the electricity grid in Jinzhai County, Anhui Province, China, and is now in commercial operation.
The Jinzhai hydro power plant project will play an important role as China strives to diversify its energy mix on the road to net zero. It comprises four 300 MW pumped storage turbines, supplied by GE to Anhui Jinzhai Pumped Storage Power Company, a division of State Grid Xin Yuan. The first two units were connected to the grid in October 2022.
The project’s annual generating capacity represents about 1.4 times the annual household electricity consumption in Jinzhai, and will help save up to 120,000 tonnes of coal and reduce 240,000 tonnes of CO2 emissions every year, according to GE.
Pascal Radue, President & CEO, GE Hydro Solutions, says: ‘Pumped storage is the largest source of energy storage that exists today, which can help stabilise the grid with the integration of wind and solar power. The Jinzhai pumped storage project, now fully operational, will provide a huge amount of clean energy to China and will help stabilise the grid to ultimately help integrate more renewable energies in a reliable way. And the beauty of hydropower projects is that it is set to be operational for the very long term, about 80 years, meaning that the project will provide affordable energy for several generations to come.’
China aims to build more than 200 pumped storage stations with a combined capacity of 270 GW by 2025, reports Bloomberg, as it aims to improve grid stability and integrate more renewable energy into the Chinese grid.
